save_an_open_page无法正常工作 - 错误消息表示找不到方法 - 但为什么？

Question

我在不同的标题下发布了此请求，并在我用信息更新请求后没有收到任何反馈。

save_and_open_page (capybara / launchy) stopped working in a project - error

我正在开发一个私人项目，我是一个单独的开发人员，学习Rails并尝试使用TDD / BDD做正确的事情，但我不得不说这个经验是想放弃测试，因为我只是没有时间花在尝试解决环境问题上。

我花了24小时的时间来试图解决这个问题。这些是我尝试过的东西：

1. 删除了Gemfile.lock并重新安装了捆绑包
2. 删除了宝石集并从头开始
3. 按照教程（M.Hartl从头开始）重建部分环境

昨晚 - 当我从本地项目切换到开始为主人更新git版本的某些功能时，-drb选项失败了（因为我还是新的，我正在运行两个项目和两个git文件夹）

我有[open_and_save_page]在本地项目中工作，但是当我在开始下一阶段交付之前运行我的规范测试一切都很好时，我遇到了与--drb有关的故障，所以我升级了当我转过防守过程时，这似乎消失了。

以下是当前错误：

我不确定我是否以正确的方式发布我的问题，就像其他一些我没有回复的问题一样。所有这些仍然是新的，这里的帮助是巨大的。所以提前谢谢。

我需要做些什么来完成第二个项目呢？

我注意到的一件事是，自从我开始将[use]放入.rvmrc文件后，当我进入目录时，我得到以下内容。

Using /Users/railsdev/.rvm/gems/ruby-1.9.3-p125 with gemset genie-bb-v3-3
Running /Users/railsdev/.rvm/hooks/after_cd_bundler 

[open_and_save_page]是水豚法吗？ launchy在哪里适合所有这些？我以为这是黄瓜相关的宝石。

Answer 1

我认为这是一个新的用户理解错误。我发现，如果我将[save_and_open_page]放在it块中，我就可以使用它。

我没有在我读到的任何文件中看到这一点，但我认为这是有道理的。
